Why should LED power supply do aging test

What is the help of the aging test before leaving the factory for the stability of the LED switching

power supply? Why do power products need to do aging test, because power products, especially for LED switching power supplies, high-frequency and high-power LED switching power supplies, aging test

is very necessary. Because the whole circuit components, with the

extension of the time of the on-load power-on test, the internal temperature of

each device will slowly rise, in the case of full load and 20% increase in

input voltage, about 20-30 minutes, the internal temperature of those key components

rises to a higher value, and the stability of the whole product reaches a height.

If some devices cannot withstand the increase in temperature, there will be accidents,

such as the output voltage drops, or the output stops, or the possibility of a component

burning black and smoking, causing certain safety hazards. According

to long-term statistical data, about 0.5% of the defective products are detected

by us at this stage, if you do not do the aging test, there is no way to detect

some of the defective power supplies that are hidden deeply. This test is a basic

test that all professional LED power supply quality manufacturers must do, Guangzhou

Yuxiang Power insists on requiring the production workshop to do 100% aging test

for each product.
